J., a corporation of New Jersey Application November 5, 1949., Serial No. 125,753 In Great Britain November'l'l, 1948 21 Claims.

of the general type disclosed in United States Letters Patent No. 2,411,827, issued on November 26, 1946 in the name of Joseph Fossa. It will be understood, however, that in certain aspects the invention is of broader scope and not limited to use in a lasting machine of the exact mechanical construction illustrated in that patent.

In the machine disclosed in the aforementioned patent, the stock to be lasted is tensioned, in diiferent locations, successively along the edge of the shoe bottom, by means of a reciprocating gripper having jaws which seize the lasting margin of the stock and pull it in a direction substantially parallel to the bottom of the shoe and over in contact with a shoe-bottom-engaging member. This patented machine is provided with means, operable in time relation to the pulling action of the gripper, for pressing the lasting margin of the tensioned stock against the bottom of the shoe in a location closely adjacent to, but spaced lengthwise of the shoe from, the gripper, and this pressingmeans is adapted, while in pressing engagement with" the lasting margin, to move in a directionto feed the shoe. Duringthose intervals when the aforementioned pressing means is out of engagement with the lasting margin, and while the gripper jaws are opened, the shoeis held against retrograde movement bya member which: also applies additional pressure to' the lasting margin.

Machines constructed in accordance with the disclosure of the above-mentioned patent have proved to be quite satisfactory and effective" in operation, particularly for use in the lasting of the platform covers, or wrappers, of so-called slip-in lasted, or platform, shoes; However; it has been found that the operation of a lasting machine of this type may be considerably improved by a modification of the tensioningmeans, or reciprocating gripper. It is, therefore, an object of this invention to provide-animproved lasting machine of the general type disclosed' in the aforementioned patent. To'this end, and in accordance with a feature of the'invention, the herein illustrated machine is provided with a novel gripper-operating mechanism by means of which the gripper, as it is moved to pull the lasting margin of the stock over the bottom of the shoe and in contact with the shoe-bottom-engaging means, is caused to travel first in apath that isinclined upwardly, away from the bottom of the" shoe, as well as inwardly from the edge of the shoe bottom, and then in a path that is inclined downwardly toward the shoe bottom. Because of this upward movement of the gripper, a greater heightwise tensioning of the stock is obtained, while the lasting margin of the tensioned stock is eventually positioned close to the bottom of the shoe, and in a suitable location to be acted on by the pressing means, as a result of the subsequent downward movement of the gripper. The advantages of this improved gripper-operating mechanism are most apparent when the stock being lasted is unusually heavy and stiff, such stock being more difficult to tension properly in a direction heightwise of the last by a pull thereon directed only inwardly of the edge of the shoe bottom and in a path substantially parallel to the plane of the bottom of the shoe, and hence resistant to being pulled in over the bottom of the shoe and tensioned in a heightwise direction.

More particularly, cam-operated means are provided for causing the gripper to move in the aforementioned upwardly and downwardly inclined path and, in order to assure that the lasting' margin of the stock will not escape from between the jaws of the gripper or that neither of the jaws will displace stock previously laid against the bottom of the shoe, means are provided for rendering the cam-operated means inoperative so that the gripper jaws return in a path that is substantially parallel, and close to the bottom of the shoe, in the same manner as in the machine of the above-mentioned patent. Preferably, and in the herein illustrated machine,

the cam-operated means includes a cam that is yieldingly supported and a member carried by the pressing means is arranged to move this cam-operated means to an inoperative position.

The above objects and features of the invention will appear in the following detailed description of a preferred embodiment thereof, illustrated in the accompanying drawings, and will be pointed out in the claims.

Referring to thesedrawings, the machine therein illustrated is, with the exception of the improved gripper-operating mechanism, of exactly the same construction as the machine illustrated in the aforementioned patent. For the purposes of simplicity, only as much of the patented machine as is necessary for an understanding of the present invention has been illustrated, it being understood that the aforementioned patent may be referred to for a description of those parts which have been omitted, or shown only in outline. To facilitate such reference and to permit a more ready understanding of the present invention, the parts of the herein illustrated machine which correspond to similar parts of the patented machine are identified with the same reference characters as were used in the aforementioned patent. Thus, the herein illustrated machine is shown as provided with a gripper having a rear jaw |U and a front jaw l2, a shoebottom rest M, a pressure-feed-foot I5, a feedretaining member l8 and an edge guide roll 20. These instrumentalities are all mounted on, and operated by mechanism contained within, a hollow head construction 22 comprising upper and lower portions 24, 26 which are indicated in part by a broken line.

The rear gripper jaw i is attached, by means of a clamping bolt 30, to a carrier 32 which is supported, in a manner to be explained below, by two rocker arms 34, 36 which are journaled respectively on cross shafts 38, 4|]. These two rocker arms are oscillated, by means including a third rocker arm 45 and mechanism which is the same as that disclosed and described in the aforementioned patent, so as to reciprocate the carrier 32 and the jaw In which is carried thereby. The front jaw I2 is carried on the end of rod I02, which is slidably mounted on the carrier 32, and is urged toward engagement with a second rod I03 by means of a spring I50. The rod I03 is operated, in time relation to the reciprocating movements of a carrier 32, by mechanism not shown but which is identically the same as that described in the aforementioned patent, so as to cause the jaws I0 and l2 to seize the lasting margin of the stock being lasted and to pull it inwardly over and in contact with a shield portion |'|0 on the shoe-bottom rest |4 thereby to tension the stock in different locations successively along the edge of the bottom of the shoe, in the same general manner as is explained in said patent.

For the purposes of this invention, however, the gripper jaws H1 and I2, instead of pulling the stock in a direction substantially parallel to the bottom of the shoe, are caused to travel first in a path that is inclined upwardly, away from the bottom of the shoe, as well as inwardly from the edge of the shoe bottom, and then to travel in a path that is inclined downwardly toward the bottom of the shoe; These movements of the gripper jaws are effected in th following manner. The carrier 32 is pivotally mounted on the rocker arm 36 by means of a stud 44 and is connected to the rocker arm 34 so as to be movable heightwise thereof while still partaking of the oscillating movements of this rocker arm by means of the following arrangement.

A channel-like member 35 is secured to the upper end of the arm 34, as shown in Fig. 3. The

carrier 32 is received by this channel-like mem-t" 4 ber and is secured thereto by means of a hemi spherical member 39 which fits into a similarly shaped recess 33, formed in the carrier 32, and which has a rib 31 that projects into a slot 3| cut in one side of the member 35. A coil spring 29 is arranged so as to hold the carrier'32 yieldin'gly down against the bottom of the channel-like member, as shown in Figs. 1 and 3. The carrier 32 is swung about its pivotal connection to the arm 35, and against the resistance of the spring 29, so as to elevate and lower the gripper jaws, during movement of the carrier to the left, in Fig. 1, by the following mechanism.

A cam member 4|, formed integrally with an arm 53, Figs. '1 and 4, is pivotally mounted, by means of a pin 55, on a face plate member 51 that is secured to the front of the frame portion 24 by means of a screw 59 and a shouldered stud 6|, see Fig. 2. This cam member has two surfaces 43 and 45 which slope, respectively, upwardly and downwardly at an angle of about 30 to the horizontal. The stud 6| passes through a slot 63 in the arm 53 and a coil spring 65, an-

chored to a portion of the head part 24, normally holds the arm 53 and the cam member 4| formed thereon elevated to the position shown in Figs. 1, 2 and 4, as determined by the engagement of the stud 6| with the arm 53 at the bottom of the slot 53. Secured to the carrier 32, in a location adjacent to the cam member 4|, is a second cam member 41 that is provided with two inclined surfaces 49, 5| which are complemental to the surfaces 43, 45 on the cam member 4|.

During the movement of the carrier 32 and the jaw ID to the left, Fig. 1, and just about at the time the lasting margin of the stock is gripped between this jaw and the front jaw |2, in the manner explained in the aforementioned patent, the surface 49 of the cam 41 comes into contact with the surface 43 on the cam 4|. Thus, as the jaws ID and I2 continue to move to the left and to pull the lasting margin of the stock inwardly over the bottom of the shoe and in contact with the shield portion ||0 of the shoebottom rest M, the surface 49 first rides up the surface 43 and then the surface 5| rides down the surface 45 and the jaws |0, |2 are correspondingly raised and lowered. Accordingly, after seizing the lasting margin of the stock, and during their pulling action, the gripper jaws are caused to travel first in a path that is inclined upwardly away from the bottom of the shoe, as well as inwardly from the edge of the shoe bottom, and then in a path that is inclined downwardly toward the bottom of the shoe while continuing their inward movement. By thus causing the gripper to pull in a direction that is inclined upwardly and away from the bottom of the shoe, a greater heightwise tensioning action is produced than could be obtained by a pull exerted in a direction parallel to the bottom of the shoe. At the same time, however, the subsequent movement of the gripper downwardly and toward the bottom of the shoe brings the lasting margin of the tensioned stock close to the shoe bottom and in a suitable position to be acted upon by the presser-feet-foot l6.

Afterthe stock has been tensioned in the above manner, and prior to gripping another portion of the lasting margin, the gripper jaws are preferably caused to travel in paths which are substantially parallel, and close to the bottom of the shoe in order that the lasting margin of the stock will not escape from between the gripper jaws and so as to avoid any tendency for either of the jaws to displace stock that has already been laid against the bottom of the shoe. In the herein illustrated machine, this is accomplished by displacing the cam member 4| to an inoperative position during such further movements of the gripper jaws as occur prior to their gripping another portion of the lasting margin of the stock. As has been explained above, this cam member is formed on a pivoted arm 53 and is held in operative position by means of a coil spring 65. For depressing this arm, against the resistance of the spring, thus to lower the cam to a position in which it is inoperative to cooperate with the cam 41 to raise and lower the carrier 32, the following arrangement is provided.

The presser-feed-foot I6 is carried by an arm 242 which is moved up and down, in time relation to the operation of the gripper, by mechanism similar to that which is disclosed and described in the aforementioned patent. An abutment 6! is secured to the arm 242 and this abutment is so constructed and arranged as to depress the arm 53 just before the presser-feed-foot [6 reaches its lowermost position in contact with the shoe bottom. .As is explained in said patent, see particularly Fig. 7 thereof, the presser-feedfoot remains in this position during the entire return movement of the rear jaw ill. The cam member 4| is thus moved down from operative position throughout the entire return movement of the rear jaw and the extent to which this cam member is depressed is such that the cam faces 43, 45 thereon are held out of contact with the cam faces 49, on the cam member 41 and the :1,

rear jaw moves rearwardly in a direction substantially parallel tothe bottom of the shoe. During such return movement of the rear jaw, the front portion of the slide 32 is held down in the channel member 35, with the rib 31 resting parts are shown in the positions assumed during an early part of the forward movement of the carrier 32 and the presser-feed-foot has risen suflicient-ly to carry the abutment 61 out of contact with the arm 53.

With the exception of the improved gripperoperating mechanism which has been described above, the herein illustrated machine operates in generally the same manner as that of the aforementioned patent. Thus the lasting margin of the stock is pressed against the bottom of the shoe, and the shoe is fed along, by the action of the presser-feed-foot I6 while the shoe is held against retrograde movement during the back-feeding motions of the presser-feed-foot and while the gripper jaws are opened, by means of the feed retainer l8.
